Up to you, but the Warthog gimbal will remain plastic ;)
After taking it apart myself to re-grease it, I'd hesitate spending that kind of money again on a Warthog.
I agree, the metal grip feels nice. The rest of it ... not so much.
Also depends if you have a tabletop setup like me, or a simpit. I like the sleek VKB design better than the bulky Warthog.
If you mainly play A-10C, then Thrustmaster it is.
